Title:
Kernel crash in nouveau with Wayland
Status in linux package in Ubuntu:
Confirmed
Bug description:
The freeze causes the mouse cursor to stop moving and keyboard to stop
responding and nothing moves on screen, not even the clock. Curiously
the music continues to play (and e.g. sound from youtube video
continues to be played even though the video itself freezes and no
longer animates on-screen).
It appears that the freeze happens quite randomly; I am not able to
figure out what it's caused by. Sometimes it's caused by launching the
Snap Chromium, or perhaps by a notification shown, but I do not know
for sure. I also tried to hunt system logs and/or systemd gnome-shell
logs, but I failed to discover some kind of crash dump.
Curiously the Ctrl+Alt+F2 key combo stops working. That leads me to
believe that it's some kind of kernel+nouveau crash, but I can't seem
to discover any kernel panic in the system logs.
After the gnome-shell freezes, the numlock light still responds to
numlock key presses. However, mashing Ctrl+Alt+Del has no effect, so
I'm only able to reboot via Alt+Sysrq+s u b.
Thank you :)
